No, we wouldn’t. We don’t use the ‘a’ or the ‘an’ in those sentences.Incidentally, you wouldn't say:
I'm a half American and a half Japanese.
I'm half an American and half a Japanese.
I'm a half American.
I'm half an American,
I'm asking this because a friend of mine, born and raised in the U.S., uses them often. She uses Japanese at home.
Yes, it's wrong, as Marsianitoh says .Hi, Loob. Then, I am a three-quarters Japanese is wrong???
(I learnt English on the same side of the pond as Loob, that's why my avatar says UK then US )As in post #2, Julian says he would say 'I am quarter Japanese, and, Loob, you would not. Maybe it's another Big Pond devide???
The ngrams are particularly clear on this - we put an article in front of quarter but not half. In the case of the glass "Ngrams not found: is quarter full, is a half full"Alternatively you could move the articles to "I'm a quarter X, a quarter Y" etc but not your version
No you can't. See #14.When it comes to 'American,' I wonder if you still can't say
I am a three-quarter American.
I met a three-quarter American.
(I know what is meant by American. Let's just put it away for now)
